When to call us in Dorney Reach
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Signs it’s time to call us include:
- Condensate trays that will not empty
- Odours coming through the supply air
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
Classrooms and halls at schools such as Dorney School are easiest to work in when pupils are away.
Questions to ask before booking
- When they can work, and whether that is outside your opening hours
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the price is fixed
- Whether they recommend a next date
How we handle AHU cleaning in Dorney Reach
If the units serving a building in Dorney Reach have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for drain trays holding standing water and odours coming through the supply air, across heating and cooling coils, supply and extract fans and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Your questions about AHU cleaning in Dorney Reach
Do you work at weekends in Dorney Reach?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Do you cover smaller places like Dorney Reach?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711 or email us.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Change filters on schedule and log each change
- Look at the condensate drain whenever the unit is serviced
- Keep the area around the fresh air intake clear
- Book the next check in line with the report
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
